The voice was a tone-producing instrument and a word-producing instrument. Both tone and word are referable to the resonator. In addition, the resonator may be closed, either partially or completely, in the formation of the consonants. It is these movements, for shaping the vowels and articulating the consonants, which are impressed on the tone. Compound vowels are divided into diphthongs and so-called triphthongs. As their name indicates, they are distinguished by the number of positions of the resonator involved. When inflection technique can be done and the principle is clearly grasped so that it responds to the intention of the author and speaker and points the meaning by inflectional variety. The sound is tone, which embodies and shows forth the emotional conception of a role. The opposite tendency is heard in the attempt to make the pronunciation of words match their spelling. This often has a most ludicrous effect, and gives rise to the expression spelling pronunciation.
